The Importance of a Good Reason to Switch to Dvorak

I've been getting a lot of Twitter messages and messages from people telling me that they have decided to switch. As a QWERTY user, looking at the VORAC, it's like a nightmare. It looks alien. Everything is- It just looks horrific. I don't promote switching just for funsies. You need to switch to Dvorak because you have a really good reason to do so. Switching because it's the more efficient layout, I think is not a good decision.
